building error on windows

[xiaochu liu]

I tried the development steps in
http://developer.pidgin.im/wiki/BuildingWinPidgin.

I downloaded and extracted everything correctly as the instruction tells
me. However, it shows an error message when I execute "building pidgin"
this step.

 gcc: The -mno-cygwin flag has been removed; use a mingw-targeted
cross-compiler.

../libpurple/win32/rules.mak:4: recipe for target `account.o' failed
make[1]: *** [account.o] Error 1
make[1]:“/cygdrive/e/devel/pidgin-devel/pidgin-2.7.11/libpurple”
Makefile.mingw:83: recipe for target `all' failed
make: *** [all] Error 2

 In the 83th line of Makefile.mingw, it is as following:

$(MAKE) -C $(PURPLE_TOP) -f $(MINGW_MAKEFILE).

I checked the environment variables in
E:\devel\pidgin-devel\pidgin-2.7.11\libpurple\win32\global.mak ,
$PURPLE_TOP $MINGW_MAKEFILE are declared clearly there. Do you have any
idea of this mistake?

(I build it in Cygwin, Windows, following the instructions in the link
above)
